I have recently purchased the alienware m15 R5. Whilst I wasn't expecting great battery life and am fine with that, and have found ways to increase the battery life, I am still only getting a predicted 4 hours battery life. I was wondering if it can be charged via the USB Type-C port on the back via a portable charger? Even if that was just a trickle, or to charge whilst turned off in a break. I have tried with a 25W charger, however it didn't even detect it. I am wondering if that is because of the low power, or the fact it doesn't support USB Type-C charging?
